[German only] Crazy successful endurance running coach writes a book containing his wisdom reached after 40 years of coaching multitudes of people towards national championships. His marathon training plan is considered one of Germany most popular ones and it’s the center-piece of the book. 250 pages of side notes broaden the picture. Some make sense, some don’t (or aren’t scientific). He was a tough coach and his writing is full of strength and funny alpha charisma. Obviously nothing special in a literary sense, but many things to take away.
